.36 v j J cri regenerators 12 and 13 serve for preheating.

As shown by the arrows in Fig. 1, air is led into regenerator 14 to be preheated to about 1000o C. in contact with the hot checker worlr and to escape through a conduit 2 into the outer end of a horizontal canal 16a extending below andacross the entire length of a row 11 of heating lues L and Z9, the first halt` ot this canal being arranged in a lower, the second half in an upper plane, a slightly ascending conduit 5a connecting the inner ends of the two halves. The hot air flows from the canal 16a through ducts 7 a into the fines a. ln a similar manner gas preheated in regeln erator 15 Vflows through a conduit 4 to the outer end of canal 16?) which extends in parallel to the canal 16a and the two halves of which are also disposed in diiferent planes, being connected by a slightly ascending conduit l5b (Fig. 4).

Duets 7?) lead from Canal 16?) to the heating tlues L and the preheated gas escaping from these ducts will mix in the fines o with the preheated air entering throughthe ducts 7 a, as described above, the mixture being burnt and they ame and waste gases iiowing through the passages 2O and downwardly through the adjoining ilues b, escape through ducts 8a and 8b at the bottom ends of these lues into two canals 17a and 17D, respectively, which lead to the regenerators 12 and 13, respectively. Canal 17a has one half extending above that halt of canal 16a, which was supplied with the air preheated in regenerator 14, and another half extending below the second halt` of canal 16a, as shown in Fig. 1, and connected with regenerator l2 by a conduit 1. The two halves of canal 17aJ are connected by a slightly descending conduit 6a (Fif 4) which crosses the conduit 5a, without, however, intersecting it, being separated from it by a wall 40 which being disposed in the middle of the oven structure is not exposed to any appreciable expansion and contraction and is therefore not liable to crack. In a similar manner canal 176 eXtends partly above and partly below the two halves of canal 166, its connecting conduit 6b crossing conduit 5?), which connects the two halves of canal 166, being v.separated therefrom by a wall 41.

As best shown in Fig. 2, each canal 16a or 166 supplies preheated air or gas simultaneously to the iiues a of two adjoining heating walls 11, the waste gases escaping from the flues b into the canals 17 a and 17 b, respectively.

0bviously, when after a predetermined interval of time the valves have been reversed, air and gas will be preheated in the regenera tors 12 and 13, respectively, in which was stored the heat of the waste gases formed in the preceding operation, and will travel through canals 17a and 17 b, respectively,h through flues b and a of adjoining heating walls, down into canals 16a and 16?) and out through regenerators 14 and 15, respectively.

In the oven illustrated in Figs. 5-7 the arrangement of superposed and intercrossing canals is similar to the one provided in the construction described with reference to Figs. 14. However, the way ot the gases diders in that the heating Walls cooperate inpairs in a well knownv manner, each heating wall being formed of a rowot` uniform flues and pairs oi' adjoining heating walls being arranged for cooperation by connecting their lues by means of conduits extending across the coking chamber flanked on both sides by the heating walls in question. It these heating walls are operated in such manner that those heating walls of two adjoining pairs, which enclose a colring chamber between them, are traversed by the `gases in the same direction, the arrangement of distributing canals described with reference to Figs. 1-4 can be simpliiied by replacing alternating superposed and intercrossed canals by a single canal, as will be described more par ticularly with reference to Figs. 5-7.

Here pairs of adjoining heating walls 33 and 34 enclose between them colring chainbers 35, the heating walls of each pair being connected with each other across such col(- ing chamber by passages 3G, one foreach flue, horizontal channels 37 common to all the lues of a heating wall and a number of U-shaped conduits 38 connecting the channels 37 oi each pair. Underneath this oven structure are arranged four regenerators 50, 51, 53, iilled with checlerworl and er;` tending in parallel across the entire length of the oven battery and at right angles to the heating walls and colring` chambers. The two outer regenerators 50, are connected by means of conduits 21, 22, respectively, with two canals 27 and 26, respectively, one half of canal 2G being superposed to one haiie of canal 27, and vice versa, and the halves of each canal being connected with each other by a sloping conduit 25 and 29, respectively,

these conduits crossing each other, without.u Such suintersecting, as shown in Fig. t. perposed canals are arranged below those coking chambers which are enclosed between communicating heating walls. Underneath each of the other colring chambers is disposed a simple canal marked 39 and 5S). respectively, the canals 39 being connected by means of conduits 24 with regenerator 52, the canals 59 by means ot conduits 23 with regenerator 51. The canals 26 and 27 communicate with n the fines 34 and l33 by means of ducts 30 and 31, respectively, canals 53 and 59 each with the ilues 33 of one and flues 34 of an adjoining pair of heating walls by means of ducts 68 and 69, respectively.

Supposing air to be supplied to regenerator 53 to be preheated therein, the hot air will flow through conduit 22, canal 2G and FII (JOI

ducts 30 upwardly in the yheating walls 34. At the same time gas supplied to and preheated in regenerator 52 will iiow through conduit 24, canal 58 and ducts 68 to mix with the hot air supplied to the heating walls 34. rllhe flame of combustion will rise 'in these heating walls andthe hot gases of com.- bustion will pass through passages 36, channels 37 and conduits 38 into the heating walls 33, descending 'therein and part thereof escaping through ducts 31 into canals 27 and through conduits 2l into regenerator .50, while another part will escape through ducts 69 into canals 59 and out through Lconduits 23 into regenerator 51, whereby these regenerators are heated up. After reversal of the valves air and gas will enter through the regenerators 50, 51, respectively, will iiowk through canals 27 and 59 and rise in the heat.- ing walls 33, the waste gases will descend through heating walls 34 and will escape through ducts 30, canals 26, conduits 22 and regenerator 53 on the one hand, and through y ducts 68, canals 58, conduits 24 and regeni erator 52.

Openings 65 in the outer Walls of the ovens communicating with the outer ends of the canals allow subsequently providing for the gas-tight sealing of the walls separating adjoining canals.
